IMPROVEMENT lN SPRING-BOTTOMS FOR WAGON-BODIES.

The Schedule referred to in these Letters Patent and making part 0f the same.

To all whom tt may concern Be it known that I, EPHnAlM D. CnAMnR, of Hackettstown, in the county of Warren and State of New J ersey, have invented a, new and useful Improvement in Spring-Bottom for Wagon-Bodies; and I do hereby -declare 'that the following is a full, clear, and ex'- act description thereotQwhich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of 'this specification.

My invention relates t0 wagon-bodies provided with spring-bottoms, and consists in an improvement upon the latter, as hereinafter described and pointed out in the claim.

In the accompanying drawing- Figure l is a vertical longitudinal section 'ot' a wagon-body provided with my improved spring-bottom, the section being taken on the-line x x ot' tig. 2.

Figure 2 is a top or plan view, partly in section.

Similar letters of reference indicate corresponding parts.

' A represents the sides, and

B, the ends of the wagon-body.

O is the spring bottom.

-D is the seat.

E and F are rollers, which are supported on pivots or gudgeons in their ends by the sides of the body.

The spring-bottom O is made of ash, or of some other tough and springy wood, slightly tapering in thickness from the seat to each end, as seen in' the The lends ot' the spring rest on the rolls E and F.

G G are pieces of leatheigor other llexible material, which are fastened by nailing, cementing, or

otherwise, to the ends of the spring and to the` rolls. l

By these pieces G Gr the spring is kept down and in place, and a slight rolling motion is imparted to the rollers as the bottom springs, thus prevent-ing any binding or friction between the spring and the rollers.

H H are cross-pieces fastened to the sides of the V wagon-body, which rest upon the axles or holsters of the running-gear, by means of which the bodyis fastened or secured to the running-gear in any suitable manner.

The spring-bottom may be made in two or more pieces, or a succession of slats may be employed for forming the bottoni. l

I do not confine myself to the particular mode shown for connecting the bottom with the rollers, as other means may be employed for that purpose.

By this arrangement the spring bottom is raised more or less from the lower edges of lthe sides of the body, according to the diameter ot' the rollers, and snticient play is allowed between the sides and the vedges of the bottom to allow the bottom to move freely up and down.

The body of the wagon, when constructed in this manner, maybe placedilow upon the axles, thus rendering the wagon much more convenient than when hung on steel springs, while all the elasticity, strength, and durability ofthe elliptic spring is secured at greatly diminished cost. v

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The end-tapered wooden spring C, flexible strips G G, and rollers E F, combined as described, to form an elastic wagon-body bottom.
